Two-step skill: (1) Map a visual Event Model diagram (image, Miro board, or screenshot) into a Markdown table with cell references, formulas, and a Mermaid diagram, then (2) generate TypeScript source files — domain types, DcbDecider per command, Projection per view, Given/When/Then tests, infrastructure repositories, command/query handlers, and TanStack Start routes — all following the DCB pattern with fmodel-decider on Cloudflare Workers. Use when the user provides an event modeling image and wants working code.

Scaffold a full-stack event-sourced application using TanStack Start, Cloudflare Workers, and the fmodel-decider DCB pattern backed by PostgreSQL via Hyperdrive. Use when the user wants to create a new project or add new domain use cases (commands, events, views, workflows) following the DCB architecture. Handles project setup, domain modeling, infrastructure wiring, UI pages, and testing with Given/When/Then specs.
